Question: 28. Interpolation When finding percentiles using Figure 3-6, if the locator L is not a whole number, we round it up to the next larger

28. Interpolation When finding percentiles using Figure 3-6, if the locator L is not a whole number, we round it up to the next larger whole number. An alternative to this procedure is to interpolate. For example, using interpolation with a locator of leads to a value that is 0.75 (or 3 4) of the way between the 23rd and 24th values. Use this method of interpolation to find for the ages of the Best Actresses in Table 3-4. How does the result compare to the value that would be found by using Figure 3-6 without interpolation?
